Steps:

1. Generate OTP:

   • Endpoint: /api/authentication
   • Description: This endpoint generates an OTP, saves it to the database associated with the phone number, and sends the OTP to the client.
   • Request Body: JSON

     {
        "phone": "+123456"
     }

   • Expected Response: Status code 200 if successful.

2. Verify OTP:

   • Endpoint: /api/authentication/verify
   • Description: This endpoint verifies a pair of phone number and OTP against the database. If the OTP is associated with the phone number in the database, a JWT token is generated.
   • Request Body: JSON

     {
         "phone": "+123456",
         "otp": 123456
     }

   • Expected Response:
     • Status code 200 and a JWT token with claim containing cardGuid if successful.
     • Error if there is no OTP associated with the provided phone number.

3. Example Usage with JWT Token:

   • Endpoint: /api/user
   • Description: This endpoint demonstrates the use of JWT token for authentication.
   • Authorization:
     • Click "Authorize" button in Swagger.
     • Paste the JWT token obtained from the response of step 2 into the "Bearer (http, Bearer)" value field.

How to Test:

1. Start by generating an OTP using the /api/authentication endpoint.
2. Verify the OTP using the /api/authentication/verify endpoint.
3. Use the generated JWT token to access protected endpoints, such as /api/user.
